100 µF, 16 V, 150 mOhm — bulk decoupling for 12 V rails
The TPSY107K016R0150: It belongs to KYOCERA AVX's TPS series, a general-purpose low-ESR family designed for power-supply filtering and bulk energy storage on rails up to 12 V.
ESR and temperature range — the real selection drivers
The 150 mOhm ESR at 100 kHz governs the ripple current rating and self-heating under AC load — for a switching regulator input capacitor, this ESR sets the ripple voltage amplitude and the I²R losses that drive the case temperature. At 100 µF and 16 V, the part handles typical buck converter input ripple without exceeding the 125°C maximum operating temperature.
2917 package — board-fit and footprint
The size code Y footprint matches the standard EIA-7343 land pattern; reflow soldering profile follows J-STD-020 for a molded tantalum with MSL 3 typical for this series.
